SUPPORT FOR CONCRETE REINFORCEMENTS.

Specification of Letters Patent.

Patented Mar. 4, 1913.

Application filed June 4,1912. Serial No. 701,694.

To all whom it may concern:

' Be it known that I, CHARLES A. KoEnNEn, a citizen of the United States, and a residentof Louisville, in the countyof J eiferson and State of Kentucky, have invented a new and Improved Support for Concrete Reinforcements, of which the following is a full, clear, and exact description.

This invent-ion relates to improvements in means for supporting concrete reinforcements, and has for an object to provide a simple inexpensive structure which not only supports the reinforcements atthe' desired place but acts as tying means for connecting the various parts together.

A further object of the invention is to provide a support Which acts in a double capacity, that of a support and a reinforcement, by reason of the diverging or radiating construction of its component members.

In carrying out the objects of the invention a blank is stamped so that when folded the same will form apl'urality of diverging supporting legs and a retaining portion which is adaptedto receive a binding wire for binding or clamping parts of the reinforced material together. The legs of the blank are designed to support the reinforced members at a proper distance from the sup port on which the legs restwhile the binding members are locked together at proper spaced intervals of the various reinforcing bars or other members.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in'

which similar characters of reference indicate corresponding partsthroughout all the views.

Figure 1 is a bottom-plan view of part of the reinforcing system of bars showing an embodiment of the invention applied thereto; Fig. 2 is a top plan view of a blank embodying certain features of the invention; Fig. 3 is a side view of a complete support embodying the form of the invention disclosed in Fig. 1; and Fig. 4 is a longitudinal vertical sect-ion through a section of cast concrete showing an embodiment of the invention in connection therewith.

Referring to the accompanying drawings by numerals, 1 and 2 indicate reinforcing bars of any desired kind, designed to reinforce a layer of concrete 3 shown inFig. 4. In order to properly space thebars 1, and 2 from the block of concrete 3, and to properly hold the same in place, a plurality of supporting members 4 are provided, having associated therewith a plurality of entwining or binding members5. The supporting members 4 areprovided with a plurality of supporting legs 6, and with notches 7 .and 8, and also with notches or cut out portions 9 and 10. In forming the support 4, the same is bent on lines 11, 12, 13, and

' 14,.Whereby the corners may be turned or bent down for forming the supporting legs 6.. When the legs 6 have been bent down'to their proper position, notches 7 and 8 are correctly in position for receiving the binding wire 5 designed to bebent over the bars 1 and 2 and entwinedor twisted, as more clearly shown in Fig. 4:. It will be observed 1. In a device of the character described,

a base formed with a body portion having a notch extending inwardly from the center of each of the four sides and bent down corners bent on aline drawn from one notch v.to the other, and an entwining member fitting into a pair of said-notches.

2. A; device of the class described com prising, a support formed of a square blank having notches in the middle of the sides and each of 'its corners bentbetween the notches about a line parallel to the diagonals of the square and an entwining bar associated with said notches in said support and projecting above the same.

3. A deviceiofthe class described comprising, a support havmgfour legs each terminating in a point, and said udjacent name to this specification in the presence of legs being substantially normal to each two subscrlbing wltnesses. other, said support having notches between Said legs and entwining member engaging a CHARLES KOERNER' 5 pair of opposite notches and ada ted to at- VVit-nesses:

tach said support in a predetermmed place. H. xC. WARREN, J r.,
